style="text-indent:25px">PFC就是功率因數(shù)校正，什么是PFC，意思是“功率因數(shù)校正”，通俗的話說(shuō)，就是提高有用功的比重。而計(jì)算機(jī)開(kāi)關(guān)電源是一種電容輸入型電路，其電流和電壓之間的相位差會(huì)造成交換功率的損失，此時(shí)便需要PFC電路提高功率因數(shù)。目前的PFC有兩種，分為被動(dòng)式PFC和主動(dòng)式PFC。被動(dòng)PFC特點(diǎn)：首先看下被動(dòng)PFC和主動(dòng)PFC在設(shè)計(jì)上有什么區(qū)別，被動(dòng)式PFC一般是一個(gè)體積較大的電感，內(nèi)部是銅線纏繞硅鋼片以絕緣膠紙包覆，外形和小變壓器非常相似。被動(dòng)式PFC采用電感補(bǔ)償方法使交流輸入的基波電流與電壓之間相位差減小來(lái)提高功率因數(shù)，被動(dòng)式PFC的功率因數(shù)只能達(dá)到0.6～0.75，一般放置在高壓濾波電容附近。被動(dòng)PFC方案簡(jiǎn)單的結(jié)構(gòu)也形成了其zui大的特點(diǎn)——低成本。主動(dòng)PFC特點(diǎn)：相對(duì)于被動(dòng)PFC簡(jiǎn)單直觀的外形，主動(dòng)式PFC電路要復(fù)雜許多。主動(dòng)式PFC電路是由電感線圈、濾波電容、開(kāi)關(guān)管及控制IC等元件組成的一個(gè)升壓電路，可以將輸入電壓提高、減少電流的電能損耗。主動(dòng)式PFC可以達(dá)到較高的功率因數(shù)──通?？蛇_(dá)98%以上，但由于電路較復(fù)雜、元件較多，所以成本也相對(duì)較高。成都主動(dòng)PFC電源批發(fā)哪家好一般來(lái)說(shuō)，功率在250W～300W的電源多采用被動(dòng)式PFC。</p><div

style="text-indent:25px">開(kāi)關(guān)電源中的pfc是什么意思？PFC就是功率因數(shù)校正，由于開(kāi)關(guān)電源不是純電阻負(fù)載，屬于容性負(fù)載，大量的開(kāi)關(guān)電源同時(shí)使用會(huì)干擾電網(wǎng)，使電網(wǎng)不平衡。一般開(kāi)關(guān)電源的功率因數(shù)PF為0.6左右。理想的純電阻負(fù)載功率因數(shù)PF為1，開(kāi)關(guān)電源經(jīng)功率因數(shù)PF校正后可以達(dá)到0.8以上！開(kāi)關(guān)電源功率因素低，會(huì)影響電網(wǎng)的使用效率，比如：10KW的電力變壓器，如果使用功率因數(shù)PF為0.6，功率1KW的開(kāi)關(guān)電源，只能同時(shí)帶動(dòng)6臺(tái)這樣的開(kāi)關(guān)電源，如果使用功率因數(shù)PF為0.9，功率1KW的開(kāi)關(guān)電源，可以同時(shí)帶動(dòng)9臺(tái)這樣的開(kāi)關(guān)電源！大量使用功率因素低的開(kāi)關(guān)電源，會(huì)將許多功率消耗在電線上，使電線發(fā)熱。還會(huì)使電網(wǎng)的正弦波失真變形，影響其它電器的正常使用。一般大功率開(kāi)關(guān)電源，都要求功率因數(shù)PF在0.8以上！對(duì)于手機(jī)充電器這樣的小功率開(kāi)關(guān)電源，沒(méi)有要求。對(duì)于LED電源，有些對(duì)功率因數(shù)也有要求。</p><p

12V輸出端接一只摩托車燈泡作假負(fù)載）即可。5、液晶電源通電后，副電源先工作，輸出+5V電壓給數(shù)字板上的CPU，此時(shí)整機(jī)處于待機(jī)狀態(tài)。當(dāng)按”待機(jī)“鍵后，CPU輸出開(kāi)機(jī)電平，PFC
